7000-year-old bricks discovered in China

Bricks dating back 5,000 to 7,000 years have been unearthed in northwest China's Shaanxi Province, adding between 1,000 to 2,000 years onto Chinese brick-making history, archaeologists claimed. "The five calcined bricks were unearthed from a site of the Yangshao Culture Period dating 5,000 to 7,000 years ago. Previously, the oldest known bricks in the country were more than 4,000 years old," Shaanxi Provincial Institute of Archaeology researcher Yang Yachang said. Only parts of the bricks, including three red ones and two gray ones, have been recovered, Yang said.

Yangshao Culture is a Neolithic culture that flourished along the Yellow River, which runs across China from west to east. The culture was named after Yangshao, the name of the first village discovered of the culture, in 1921 in central China's Henan Province. Archaeologists used to believe the ceramics were applied to architecture in the Shang Dynasty (1600 BCE-1100 BCE), which had been proved wrong by the new discovery, Yang said....
